The information in this page is updated in accordance with firmware version TRB2M_R_00.07.15.1.
Summary
BACnet is a communication protocol for building automation and control (BAC) networks that use the ASHRAE, ANSI, and ISO 16484-5 standards protocol.
This manual page provides an overview of the BACnet functionality in TRB246 devices.
Note: BACnet is additional software that can be installed from the System → Package Manager page.
General Configuration
| Field | Value | Description |
|---|---|---|
| Enable | off | on; default: off | Enables BACnet router function. |
| Enable BBMD | off | on; default: off | Enables BACnet broadcast management function. |
| BBMD port | integer [1..65535]; default: 47808 | BACnet broadcast management devices port. |
| BBMD interface | network interface; default: br-lan | Specifies interface for BBMD function. IP address of this interface should be reachable from WAN. |
| Allow Remote Access | off | on; default: off | Creates port forward firewall rule to make application port in LAN reachable from selected BBMD interface. |
| Force gateway | off | on; default: off | Adds configured gateway IP address and port to BBMD packages sent. |
| Gateway address | ip4; default: none | Gateway IP address. |
| Gateway port | integer [1..65535]; default: none | Gateway port number. |
BDT Configuration
This section contains Broadcast Distribution Table (BDT) configuration, where you specify the list of BBMDs (BACnet Broadcast Management Devices) responsible for forwarding broadcast messages between different subnets in a BACnet/IP network.
| Field | Value | Description |
|---|---|---|
| IP address | ipv4; default: none | IP addresses of the BBMDs in the network. |
| Port | integer [1..65535]; default: none | Port numbers on which the BBMDs listen for BACnet/IP messages. |
| Netmask | netmask; default: none | Subnet masks used by the BBMDs to determine the range of IP addresses within a subnet. |
| Actions | -interactive button; default: delete | Deletes BDT configuration. |
BIP Configuration
Communications in BACnet over IP (BIP) rely upon the protocol rules of IP and Ethernet.
| Field | Value | Description |
|---|---|---|
| Network ID | integer [1..65535]; default: 1 | Unique identifier for the BACnet/IP subnet within the entire BACnet internetwork. |
| Port | integer [1..65535]; default: 47808 | This specifies the port number used by BACnet/IP devices for communication. |
| Device | interface; default: br-lan | Select the network device to be used for BACnet/IP communication. |
| Actions | -interactive button; default: delete | Deletes BIP configuration. |
